The difference between biological safety cabinets and fume hoods and clean benches
Biosafety cabinets are widely used in health care, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring, and various biological laboratories. They are an important foundation for ensuring biosafety and environmental safety. Fume hoods and clean benches are not biosafety cabinets and should not be used in experiments or production processes involving microbial materials.
How To Pick The Right Fume Hood And Biological Safety Cabinet For You And Your Lab
Fume hoods are ventilated enclosures that remove hazardous chemical fumes and volatile vapors from a laboratory, providing only personnel protection. Biosafety cabinets utilize HEPA filters to provide environmental, personnel and/or product protection.
Depending on your application, they can recirculate or exhaust filtered air and are suitable for dealing with harmful particles such as bacteria and viruses.
Features And Maintenance Of Class II Biological Safety Cabinets
Class II biological safety cabinets can prevent the spread of harmful aerosols and aerosols; provide protection for operators, samples and the environment. A better environment should be selected for the machine before commissioning. It is good to place it in a sterile room with air disinfection facilities. If the conditions are not available, the machine should be placed in a cleaner room with less movement of personnel. Adjust the height of each foot to ensure a stable and level operating surface. A special circuit should be used for the power supply of the workbench to avoid changes in the air flow rate caused by circuit overload.
